Answer:
Pair 1
Explanation:
The poles are opposite, so opposite closer together and the distance is closer together, so there is stronger magnetic field
The pair of magnet that have the greatest magnitude would be Pair 1.
Why do they have the greatest magnitude ?Magnets will only attract each other and therefore have a great magnitude if they are facing opposite poles. Pair 3 are therefore out because it has the same pole facing the other.
Magnitude of magnetic force will increase the closer the magnets are to each other. Seeing as Pair 1 has the lowest distance of 0. 3 cm, it means that Pair 1 would have the greatest magnitude.

Answer: Encourage students to set up a germination experiment by placing the seeds in different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to pot the same seed in more than one pot.
Explanation:
This option provides a clear and practical approach to the seed germination investigation. By setting up different conditions for the seeds, such as light vs. dark or wet vs. dry, the students can observe and compare how these conditions affect the germination process. Additionally, potting the same seed in multiple pots allows for a controlled comparison within the experiment.
By manipulating these variables, the students can gather valuable data and observations regarding the influence of light and moisture on seed germination. This approach promotes a hands-on and investigative learning experience, encouraging students to actively engage with the scientific process while documenting the changes that occur over time, such as the emergence of roots and shoots.

The addition of yeast into bread dough makes it raised by increasing its volume, and the growth of fungus takes place on bread slide when it is left for a longer time in moisture. A researcher took samples from the dough of bread on slide A, and from old bread on slide B. The researcher observed the growth of these organisms under the microscope. What type of asexual reproduction might have been observed by the researcher on both the slides?
Answer:
The correct answer is 'Saccharomyces cerevisiae'.
Explanation:
Bread dough is made using yeast. As the dough ferments, carbon dioxide is created and trapped as microscopic air bubbles. It increases as a result. The expansion of carbon dioxide during baking allows the bread to rise higher. Baker's yeast, commonly known as Saccharomyces cerevisiae, is used to make many different bakery goods in addition to bread.
It is employed in the fermentation process, which yeast performs on the sugar and starch in the flour. Fermentation transforms the starch into alcohol and carbon dioxide.
After baking, the carbon dioxide in the dough gives the bread its softness and fluffy texture. It also causes the dough to rise.

Picture C, where each pair of sister chromatids attaches to a spindle fiber by its centromere.
Picture D, where chromosomes coil up, nuclear membrane breaks down, and spindle fiber system forms.
Answer:
The illustration of anaphase stage of mitosis is where the spindle fibers start to pull away from the center of the cell.
MITOSIS:
Mitosis is the process whereby a single cell results in two daughter cells that are genetically identical to one another.
Mitotic division occurs in stages namely: prophase, metaphase, anaphase and telophase.
Prophase: Condensation of chromatids to more visible X-shaped structure called chromosomes.
Metaphase: Chromosomes line up at the cell's equator
Anaphase: Chromosomes are pulled apart by the spindle fibers that attached to their centromere.
Telophase: Reformation of the nuclear membrane.
According to this question, in the anaphase stage, spindle fibers start to pull away from the center of the cell to separate the chromosomes.

List 3 negative impacts does plastic pollution have on the ocean?
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.
